Quantum Network Between Two National Labs Achieves Record Synch

Key Facts

The experiment marked the first time that quantum-encoded photons — the particle through which quantum information is delivered — and classical signals were simultaneously delivered across a metropolitan-scale distance with an unprecedented level of synchronization.
They showed that it is possible for quantum and classical signals to coexist across the same network fiber and achieve synchronization, both in metropolitan-scale distances and real-world conditions.
To assure that they get pairs of photons that are entangled — the ability to influence one another from a distance — the researchers must generate the quantum-encoded photons in great numbers.
Now the IEQNET team is preparing to perform experiments to demonstrate a process that enables entanglement between photons from different entangled pairs, thus creating longer quantum communication channels.
